Hi,
In prints where I use a raft, the first layer after the raft seems to be printing higher than it should have been. This results in supports being broken at this height or not being able to be printed at all. Is there a setting to modify the height of the first layer after the raft?

Re: First layer height following raft
"edit process settings", click Additions tab, decrease your raft separation distance.
That will move the part closer to the raft and decrease the gap

Thanks for the information JoeJ. That works perfectly...
Re: First layer height following raft
Hi, hijacking this thread =)
I'm fairly new to Simplify3D but I've been struggling with the first layer after the raft inorder to get good separation between the part and the raft.
I've been using a Zortrax M220 which we have in my work office, it has it's own closed slicer etc but does rafts and raft separation really nice (prints almost everything perfectly!).
The simplify 3D seems to have indentical raft base implementation as the Zortrax, but the end result is quite less satisfactory, hard to separate the raft from the part... or messy first layer after raft if trying to increase the sep. distance.
I've been analyzing the Zortrax in great detail in how it goes about doing the raft, and in-order to mimic it's behavior I would need to be able control the following things (for the first layer after raft independetly from all other layers).
1. Perimiter Temperature vs solid base temp (Zortrax seems to print the infill first with lower temp, then the perimeter last with higher temp, such that the only things that sticks alot is the perim (easier separation).
2. Speed (SF3D seems to speed up the print speed for this layer, which causes problems when raising the separation distance).
3. Infill before perim only for this layer (think SF3D does this right actually).
Could this be possible to acheive in SF3D 3.0?
I've tried to have a separate process for only this layer, but the SF3D seems to screw things up when using the layer offsets while simultaneously having a raft in the first process!? I might be doing something wrong...
I really need to get the rafts going on my home printer. Using the rafts allows me to have the part stick really well (perforated PCB) while lowering the heated bed temperature alot (which in turn keeps the parts from curling up).
